• MU: The MU number of the P-VOL.
• Status: The status of the P-VOL.
• S-VOL: Information about S-VOL is displayed in AAA-BB-CCC(XX:YY:ZZ) format.
• AAA: The port ID (cluster and channel number)
• BB: The group number of host group
• CCC: LU number
• XX:YY:ZZ: LDKC number:CU number:LDEV number
Note: An LDEV number that ends with a # mark indicates that the LDEV is an external volume
(for example, 00:00:01#). An LDEV number that ends with a letter X indicates that the LDEV is
a virtual volume used by XP Thin Provisioning (for example, 00:00:01X). For details regarding
the external volumes, see the HP StorageWorks XP24000 External Storage Software User’s
Guide. For information about Dynamic Provisioning, see the HP StorageWorks XP24000 Thin
Provisioning Software User's Guide.
• Emulation: The emulation type of the P-VOL and S-VOL.
• Capacity (MB): The volume capacity displayed in megabytes (MB).
• CLPR(P): The cache logical partition of the P-VOL.
• CLPR(S): The cache logical partition of the S-VOL.
• The Copy Pace drop-down list allows you to select the copy pace (from Slower, Medium, or
Faster) for all pairs being created. By clicking the Set button, the same copy pace will be applied
to all the new pairs being created.
Notes:
• When the Preview List already holds some Paircreate settings, and you specify a different
copy pace for new pairs in the Paircreate dialog box, the copy pace for the existing Paircreate
settings displayed in the Preview List will be also changed. The latest copy pace specified in
the Paircreate dialog box is in effect before the settings are reflected to the storage system.
• If you specify Slower, the pace of initial copying will be slow, but you can minimizes the
impact of Business Copy operations on storage system I/O performance. If you specify
Faster, the initial copy operation completes as quickly as possible, but it will cause a large
impact on the I/O operation.
• The Select MU drop-down list allows you to select the MU number for each pair being created
from: 0, 1, and 2 for L1 pairs, and 1 and 2 for L2 pairs.
Notes:
• When a P-VOL makes a pair with more than one S-VOL, the storage system assumes that there
are same numbers of virtual P-VOLs. For example, when a P-VOL makes pair with three
S-VOLs, there is only one real P-VOL but the storage system assumes that there are three virtual
P-VOLs. Virtual P-VOL is called MU (Mirror Unit).
• You can select an MU number for a cascade pair. You cannot select the same MU number for
different cascade pairs of the same P-VOL (root or node volume).
• If you specify the MU number that is already used for XP Snapshot pair, or if you specify
MU number 0 for L2 pair, an error occurs.
• The Select S-VOL box allows you to filter the S-VOLs displayed in the S-VOL List located on
the right.
• The
Port drop-down list allows you to select the available S-VOLs by port
• The Volume Type box:
The Internal VOL check box allows you to select the available S-VOLs that are internal volumes.
The External VOL check box allows you to select the available S-VOLs that are external
volumes. Note that you need the External Storage features to select the external volumes.
• The Attribute box allows you to select the available S-VOLs that are reserved when the
Reserved check box is selected, or those that are unreserved when the Not Reserved check
box is selected. The Attribute box also allows you to select the pairs that can be set as L2
pairs when the Pair check box is selected.
